This function imports and converts a SIF file from your local hard drive, cloud space, or internet into a graph with an igraph class, which can then be used for the identification of most influential nodes via the ivi function, for instance.

sif2igraph(Path, directed = FALSE)



A string or character vector indicating the path to the desired SIF file. The SIF file could be on your local hard drive, cloud space, or on the internet.


Logical scalar, whether or not to create a directed graph.


An igraph graph object.
